Abstract

The present invention integrates a direct-to-home satellite Internet service with a mobile broadcast service via a hand-held caching terminal that accesses multiple return-link paths through the available cellular infrastructure or through the satellite to the Internet and to a home-PC-based server.

Claims

1. ) A direct-to-home-and-mobile satellite internet service system comprising:

a) a hand held mobile terminal comprising a large data cache with two way communication links comprising a local link and a satellite link to a user'"'"'s server,

b) a gateway providing two way communication from the hand held mobile terminal to the server and

c) a geo satellite providing two way communication and mobile broadcast services through the gateway.

2. ) The system as defined in claim 1 wherein said server comprises a personal computer.

3. ) A direct-to-home-and-mobile satellite internet service system comprising:

a) a hand held mobile terminal

b) a gateway providing two way communication from the hand held mobile terminal to a server and

c) a geo satellite comprising a combination of payload elements providing two way communication and mobile broadcast through the gateway.

4. ) The system as defined in claim 3 wherein said server comprises a personal computer.

6. ) The system as defined in claim 3 above wherein the gateway comprises a large antenna which provides smaller spot beams employing a large degree of frequency.

7. ) The system as defined in claim 3 above wherein said gateway employs a greater number of receive beams than transmit beams illuminating a user coverage area.

8. ) The system as defined in claim 3 above wherein said transmit and receive beams are separated into two antennas.

5. ) A direct-to-home-and-mobile satellite internet service system comprising:

a) a hand held mobile terminal

b) a gateway comprising a user monitor which tracks a transmit beam to provide hand-off between two transmit signals when a first beam moves off the user and a second beam moves on to said user, and

c) a geo satellite providing two way communication and broadcast through the gateway.

9. ) A direct-to-home-and-mobile satellite internet service system comprising:

a) a geostationery communications satellite comprising a multi-band payload

b) a gateway with Internet point-of-presence providing a multiplicity of services, and

c) a mobile user terminal which receives broadcasts from said satellite and communicates through terrestrial wireless systems or satellite to the gateway and a server.
